Engine oil usage/burn rate

This is my first summer with our new 2008 Centurion Enzo 230 6.2L 377ci w 400hrs on the clock. We seem to be burning oil at a faster rate than I would normally be comfortable with. We are starting to keep track more carefully, but initial observations have us using 1qt for our first 10hrs of use. No smoke, no residue in exhaust, oil pressure good. We have not checked compression yet, but we will. I have spoken to mechanics from different makes from coast to coast and a tech at Mercruiser and Centurion. All but one have assured me that the way we use these boats (weighted for boarding, and tilted when surfing) will lead to oil burning. They say the big blocks suck it down even worse. I am willing to accept this, but would feel better if others experience the same thing. I have checked a lot of forums and sites, and do not see much discussion on the topic, which surprises me. If my car or 1999 Mastercraft did this, I would be freaking out. Actually there was a certain amount of panic when we first realized we were burning oil. Any thoughts or other clues we should look for would be appreciated. thanks
